For me (not the guy you responded to) the big thing is shoes. When I find a pair I like I’ll often buy two or three extra pairs (often online) in other colorways but when those wear out they usually aren’t made anymore or I want to try something new. Boots and shoes (especially rock climbing shoes) seem to never be consistently sized, even inside the same brand, and I need to try them on to get them to fit right. Can’t really think of anything else off the top of my head!

I don't understand the sizing problems with shoes at all. I elaborated in another comment: https://news.ycombinator.com/item?id=36256573.

I do find shoes sometimes have inconsistent sizing between brands, but they usually say something like "runs 1/2 size small". Worst comes to worst I can compare size charts with a pair that I already own.

It's never a crapshoot where I can't rely on their sizing at all.
